Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142824, here are decompositions:
- 13 + 142811 = 142824
- 37 + 142787 = 142824
- 53 + 142771 = 142824
- 67 + 142757 = 142824
- 113 + 142711 = 142824
- 127 + 142697 = 142824
- 151 + 142673 = 142824
- 167 + 142657 = 142824
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,824 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142824 first appears in π at position 132,065 of the decimal expansion (the 132,065ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
